This data was collected by Google and Dublin City Council as part of [Project Air View Dublin](https://smartdublin.ie/google-and-dublin-city-council-launch-innovative-partnership-to-capture-dublins-air-quality-street-by-street/). Google's first electric Street View car equipped with Aclima’s mobile air sensing platform drove through the roads of Dublin City measuring street by street air quality. Driving predominantly took place Monday–Friday between 9:00 am and 5:00 pm from May 2021 through August 2022, so the dataset primarily represents typical daytime, weekday air quality. The car measured pollution on each street and highway at 1-second intervals, driving with the flow of traffic at normal speeds. The pollutants determined are: Carbon Monoxide(CO), Carbon Dioxide(CO2), Nitrogen Dioxide (NO2), NO (nitric oxide), Ozone (O3), and Particulate Matter PM2.5 (including size resolved particle counts from 0.3 - 2.5 μm). Airview_DublinCity_Measurements is the 1-second intervals data captured during the period. AirView_Dublin_City_RoadData is the 1-second data points aggregated in approximately 50m road segments.
